Summary

During infiltration of ceramics by molten metals at high temperatures, interfacial chemical reactions, metal oxidation, pore modulation and closure, and transient capillary forces due to contact angle evolution could all play an important role in controlling the flow. The role of these factors is discussed in the context of infiltration of ceramic/metal composites. It is suggested that the effect of some of these factors may be modeled by modifying the classical theory of capillary flow of inert liquids.
